L-shaped retaining walls at outer sides are utilized for effectively limiting probability of arbitrary swinging of the terminals, thus being beneficial to injection molding operation in post processing procedure; the exposed length of the terminal can be effectively controlled, thus leading the terminal to be in accordance with the requirements of safety standard.

The invention discloses an oil scraper ring, which comprises a circular body. An oil storage groove is formed in the upper end part of the body. The inner wall of the body is a scraping wall. The outer wall of the body is a retaining wall which is higher than the scraping wall. According to the scheme, the retaining wall is higher than the scraping wall, and when the oil scraper ring rotates along with a piston or a piston rod, lubricating oil in the oil storage groove can be prevented from being splashed from the oil storage groove under centrifugal force generated by rotation; and in addition, the bottom surface of the oil storage groove is an inclined surface, and the bottom surface close to the retaining wall is lower than the bottom surface close to the scraping wall, so that the center of gravity of the lubricating oil in the oil storage groove is close to the retaining wall, and the oil scraper ring difficultly rotates or rotates at low speed to favorably prevent the lubricating oil from being splashed from the oil storage groove. According to the scheme, scraped lubricating oil cannot flow out of the oil storage groove, so that the backflow of the lubricating oil is effectively prevented, and an oil leakage phenomenon is avoided to reduce the oil content of air in a piston type air compressor and ensure the purity of the air in the piston type air compressor.

The invention discloses a lifting and pulling gate of a telescopic vertical column. A vertical column side clamping groove and a vertical column upper clamping groove are symmetrically formed in bothsides of the vertical column. The water retaining gates are arranged in the vertical column side clamping groove and the vertical column upper clamping groove in a sleeving and sealing mode. Embeddedguiding water retaining walls are separately located at the two sides of the water retaining gates. Sealing sliding ways are separately arranged on the two inner side walls of the embedded guiding water retaining walls. The two sides of the water retaining gates are installed in a sealing mode in the corresponding sealing sliding ways and can slide. A lifting mechanism capable of driving the lifting movement of the vertical column is arranged on the inner side of the foundation below the vertical column. The lifting mechanism is arranged under the foundation, the vertical column is driven to move up or down by the lifting mechanism, when the flood comes, the telescopic vertical column rises automatically and extends out of the gate to resist the flood, and the problem that a garage, an underground parking space, a shopping mall, an underground space entrance are damaged caused by overflow of water from an entrance and an exit is avoided.

The invention provides a soil retaining structure suitable for eliminating a frost heaving effect in a cold region and a construction method. The soil retaining structure comprises a slope protection backfill material, an EPS-containing mixed structure, a wall heel clay layer, a retaining wall, a drainage hole, a rigid pull rod and an anchoring plate; a through drainage hole is formed in the upper portion, the middle portion and the lower portion of the retaining wall body; the backfilling structure for eliminating the frost heaving effect is tightly attached to the wall back; the left ends of the rigid pull rods are embedded into the retaining wall, and the right ends of the rigid pull rods transversely penetrate through the EPS light soil to be connected with the anchoring plate in the soil embedded behind the wall; and the construction method comprises the following steps of construction preparation, foundation trench excavation and construction working face building, construction of the retaining wall and the backfill structure behind the wall, construction of the rigid pull rod and construction of the EPS-contained mixed structure.
